react-router-dom V6实现简单的路由鉴权

一、创建一个鉴权的组件，进行鉴权判断逻辑

下面是判断是否登录的简单实现

import React from 'react'
import { useSelector } from 'react-redux'
import { Navigate, useLocation } from 'react-router-dom'

const AuthRouter = ({ children }) => {
    const token = useSelector((state) => state.token)
    const location = useLocation()
    if (token) {
        return children
    } else {
        return <Navigate to='/login' replace state={{ from: location }}></Navigate>
    }
}
export default AuthRouter

二、在路由文件中将需要进行登录判断的路由进行组件包含

import { lazy } from 'react'
import { Navigate } from 'react-router-dom'
import AuthRouter from './AuthRouter'
const Index = lazy(() => import('../views/Index'))
const Login = lazy(() => import('../views/Login'))
const Error = lazy(() => import('../views/Error'))
const routes = [
    {
        path: '/',
        element: (
            <AuthRouter>
                <Index />
            </AuthRouter>
        )
    },
    {
        path: '/login',
        element: <Login />
    },
    {
        path: '/error',
        element: <Error />
    },
    {
        path: '*',
        element: <Navigate to='/error' replace />
    }
]
export default routes

三、App.js中进行路由的加载和组件的懒加载

import React, { Suspense } from 'react'
import { useRoutes } from 'react-router-dom'
import routes from './router'
import PageLoading from './components/PageLoading'
const App = () => {
    const routeList = useRoutes(routes)
    return (
        <>
            <Suspense fallback={<PageLoading />}>{routeList}</Suspense>
        </>
    )
}
export default App

如上当未登录时，访问/时，就会自动跳转到 /login
